SKF 61821-2RZ deep groove ball bearing
Code: 318515
Product detailed description
SKF bearing 61821 2RZ - non-separable single-row radial ball bearing with a steel cage guided by balls with low-friction seals on both sides and normal radial clearance. The seals of the 61821 bearing are made of oil-resistant and abrasion-resistant rubber, which is vulcanized to a metal reinforcement and are pressed into grooves in the outer ring. The sealing blades create a very narrow gap with the smooth inner ring. Due to the low friction, bearings with this seal can operate at the same speeds as bearings with Z-shields, but the sealing effect is higher. The 61821-2RZ bearing is filled with high-quality lubricant with a temperature range from -40 °C to +100 °C and briefly up to +120 °C.Additional parameters
